The Allegro ACS725LLCTR-30AB-T is an economical and precise Hall effect current sensor IC suitable for AC or DC current sensing in various systems. It features a differential Hall sensing mechanism that rejects common-mode fields, improving accuracy in noisy environments. The device has a primary conductor resistance of 1.2 mΩ, resulting in low power loss and high inrush current withstand capability.
Key electrical specifications include a 30A current rating, a sensitivity of 44mV/A, and an accuracy of ±0.7%. The sensor operates with a voltage range of 3V to 3.6V and offers a high bandwidth of 120 kHz for fast response times. The output is ratiometric and proportional to the current, with bidirectional polarization.
This current sensor IC is provided in a small, low-profile 8-SOIC surface-mount package, making it ideal for space-constrained applications. The terminals of the conductive path are electrically isolated from the sensor leads, enabling high-side current-sense applications without the need for costly isolation techniques.
Typical applications include motor control, load detection and management, switched-mode power supplies, and overcurrent fault protection. The AEC-Q100 qualification indicates its suitability for automotive applications.
